Embodiment Construction

[0069] In the following detailed description, by convention, the "axial" direction corresponds to the direction of the axis of rotation of the molding machine, and the "radial" direction is orthogonal to the axial direction.

[0070] In general, the invention relates to the field of manufacturing containers of thermoplastic material, such as bottles of PET (polyethylene terephthalate), using preforms.

[0071] Such hollow containers are used especially, but not exclusively, in the field of agro-food processing for packaging liquids such as water, milk, fruit juices and the like.

[0072] Its manufacture is carried out in a container manufacturing plant which additionally has a molding machine 10 for molding with a hot preform, more generally with a rough blank constituting a special case of the preform. Made of thermoplastic material containers.

[0073] figure 1 An embodiment of such a molding machine 10 (also referred to as a "blow molding machine") is schematically shown ...

Abstract

The invention relates to a method for cooling heated molds from a machine for molding containers, particularly a method for cooling heated molds from a machine (10) for molding containers from thermoplastic material by stretch-blow molding hot preforms using at least one pressurized fluid. The cooling method is characterized in that the method comprises, in order to cool the molds (18), at least one cooling step that involves selectively feeding at least one cooling fluid into the molding cavity (16) of at least some of the molding units (12) that, after the carousel (14) has been stopped in order to immobilize the molding units at least during the cooling step, are located in a predetermined cooling region in which the molding units (12) are in a closed position.

Description

technical field [0001] The present invention relates to a cooling method for cooling a heated mold of a container molding machine. [0002] More particularly the present invention relates to a cooling method for cooling a heated mold of a molding machine for molding thermoplastic A material container, a rotary molding machine having at least a plurality of molding units each having at least one mold, the molding units being arranged on the periphery of a turntable that can be driven around the The axis of rotation rotates, each molding unit has at least a blowing part, the blowing part is integrated with a stretching rod, each molding unit also has a heating part, the heating part is combined with said at least one mold of the molding unit to heat the Said mold, said mold has at least two half-molds, said at least two half-molds each have a molded inner surface and are respectively mounted on a support, the support can be around the axis in at least the mold opening position ...
